CVE-2026-97511— wifi: mac80211: avoid out-of-bounds access in monitor

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： wifi: mac80211：避免在监控模式下发生越界访问 在 NAN（Neighboring Awareness Network）场景中，我们无法确定数据帧将在哪个频段（band）上发送。因此，我们将 设置为 。然而，当尝试访问 数组时，这会导致在 函数中发生越界访问。 修复方法是：如果频段为 ，则不访问该数组。这意味着在 NAN 场景下，我们将不再报告传统速率（legacy rate）的信息。但事实上，这一细节并无实际影响，因为无人关心此信息。

Vulnerability Title
wifi: mac80211: avoid out-of-bounds access in monitor
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: avoid out-of-bounds access in monitor In NAN, we don't know on what band the frame will be sent. Therefore we set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound access in ieee80211_add_tx_radiotap_header when we try to access the sbands array. Fix it by not accessing the array if the band is NUM_NL80211_BANDS. This means that we will not report rate info for legacy rate in NAN. But nobody really cares about it.
